When Mt. St. Helens erupted it spewed tons of volcanic ash for miles in every direction.� When this ash is fused in a laboratory at 2700 degrees in an oxygen-free environment it forms obsidianite. The lovely emerald color is caused by a combination of copper, chromium and iron in the ash.� We have many different cuts and sizes of the earrings show here.
